geno-, gen-, genit-, gener-, -gen

(Greek > Latin: race, kind; line of descent; origin, creation; pertaining to sexual relations, reproduction, or heredity; and more recently, a gene or genes)

lactogenesis

leukemogenesis

lipogenesis

1. The formation of fat; the transformation of nonfat food materials into body fat.
2. The production of fat, either fatty degeneration or fatty infiltration; also applied to the normal deposition of fat or to the conversion of carbohydrate or protein to fat.
3. The production of fat by the body; adipogenesis.

lipogenic, lipogenetic, lipogenous

1. Forming, producing, or caused by fat; relating to lipogenesis.
2. Of or relating to the production of fat.

lithogenesis

Formation of calculi.

lysogenesis

macrogenesis

A sudden mutation producing a heritable variation in the morphology of a species that occurs more abruptly than other instances of comparable change and is difficult to explain through natural selection.

Something that is done quickly by the husband for his wife: When Jack's wife wanted to go to a beautician to get her hair trimmed and enhanced, he made a maritogenous action to get their car out of the garage and take her to the hair stylist in time for the scheduled appointment.

melanogenesis

merogenesis

1. Reproduction, or multiplication, by segmentation.
2. Cleavage of an ovum.

metagenomics; Environmental Genomics, Ecogenomics, Community Genomics

1. The study of the collective genomes of microorganisms (as opposed to clonal cultures).
2. The study of genomes recovered from environmental samples as opposed to getting them from clonal cultures.

The technique is to clone DNA in large fragments directly from the microorganism's environment; (soil or oceans) into a culturable host and conduct a sequence-based and functional genomic analysis on it.

The hope of this new strategy is isolate new chemical signals, new secondary metabolites that might have utility to humans, and the reconstruction of an entire genome of an uncultured organism.

This relatively new field of genetic research allows the genomic study of organisms that are not easily cultured in a laboratory.

In 1998, Jo Handelsman, a plant pathologist at the University of Wisconsin-Madison and four colleagues coined the term metagenomics, literally, "beyond genomics".

Metagenomics has also been described as "the comprehensive study of nucleotide sequence, structure, regulation, and function".

Scientists can study the smallest component of an environmental system by extracting DNA from organisms in the system and inserting it into a model organism. The model organism then expresses this DNA where it can be studied using standard laboratory techniques.

The production of colorless, gaseous, inflammable hydrocarbons with living organisms: "Methanogenesis is the formation of methane from microbes that exist in fresh-water or marine sediments, in the intestinal tracts of animals, or in places constructed by humans; such as, sludge in sewage or biomass digesters all of which come from the anaerobic microbial food chain."

"In biotechnology, methanogenesis is the last step in the artificial production of methane, during which hydrogen and bicarbonate are processed into methane."
